We present the first steps to develop radiation sensors based on the graphene field effect transistor technology. Such a sensor exploits the ambipolar behavior of graphene near its Dirac point and it is not dependent on collecting charges, but it senses io ...
GaN-based electronic devices have great potential for future power applications, thanks to their wide band-gap, high breakdown electric field, and high electron mobility. In addition, these devices can be integrated on large-size Si substrates and enable n ...
Conductive inks consisting of graphene and carbon black conductive fillers into a polydimethylsiloxane (PDMS) matrix, which can be processed into thin films by screen printing are developed. The influence of filler composition and content on mechanical and ...
Buoyancy driven flows such as gravity currents, present in nature and human made applications, are conveyors of particles or dissolved substances for long distances with clear implications for the environment. This transport depends on the triggering condi ...
The low ON-resistance of wide-band-gap (WBG) transistors is a key feature for efficient power converters, however, the anomalous loss in their output capacitance (COSS) severely limits their performance at high switching frequencies. Characterizing COSS-lo ...
One approach to overcome the high contact resistance between 3D metals and 2D materials/heterostructures is employing edge contacts [1]. A low-resistance edge contact on boron nitride/graphene/boron nitride heterostructure using photolithography has been d ...
III-V nanowires (NWs) have a great potential for solar energy applications due to their diameter-dependent optical properties, which may enhance absorption of light. In addition, core-shell radial p-i-n structures, in which the direction of light absorptio ...
In Atomic force microscopy (AFM), the tip-sample interaction force can be measured
through two primary detection techniques: optical beam detection (OBD) and electrical (self-sensing)
readout. Compared to the optical method, the convenience of the self-sen ...
The growing research on two-dimensional materials reveals their exceptional physical properties and enormous potential for future applications and investigation of advanced physics phenomena. They represent the ultimate limit in terms of active channel thi ...
The intrinsic characteristic of a permanent magnet synchronous motor is defined by its internal dimensions, its material properties, as well as the power supply used in conjunction with the motor. When an extended operating range is desired but the electro ...
